Question

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.

What is the measurment of

Answer 1

74

Explanation:

Since a translation is a rigid transformation, it preserves side lengths and angle measurement.

Thus We know that

A's is 80 and C' is 26.

Use Triangle Interior Theorem to find Angle B.

`180 - 80 - 26 = b`

`74 = b`
